DISPENSER Feb. 12, 1957 Filed Aug. 11, 1954 INVENTOR 1 Awe/4 lee 1 4 S/L/k ATTORNEY tates Unite This invention relates -to a new and useful improvement in the dispensation of pressurized material and more particularly to a dispensing mechanism and a cabinet structure in combination with a pressurized container to be utilized in dispensing products for domestic, industrial and service institutions.

Historically the dispensing of toothpastes, shaving creams, soaps, hand lotions, mayonnaise, shortening and the like in the home, industries, and service institutions has been primarily a squeezing, pouring or dipping operation. In some instances gas bombs have been devised for spraying liquids such as insecticide. These liquids are contained in containers which when once utilized are thrown away. These previous containers do not comprise a practical permanent unit from which the dispensing of pressurized powder and fiuidproducts used in the home, industrial and service institutions can be accomplished with convenience, safety, and economy.

An object of the present invention lies in providing, in combination, a pressurized container containing material to be dispensed, a cabinet or support for this pressurized container, and a dispensing apparatus forming a part of the cabinet or support and arranged to control the flow of the material dispensed.

A further feature of the present invention lies in the provision of a support arranged to accommodate a container of pressurized flowable material which may be in solid, semi-solid, or liquid form. The support includes dispensing mechanism in the form of a dispensing pas sage communicating with the pressurized container outlet when the container is in place upon the support, and also includes a means of controlling the flow of the pressurized material.

A further feature of the present invention lies in the provision of a support to which pressurized containers may be detachably secured. The structure is such that all of the material within the pressurized container must flow through a portion of the support. At the comple tion of the dispensing operation, the empty container may be removed and replaced by a full container.

A further feature of the present invention lies in the provision of a means of automatically opening the pressurized container as the same is mounted upon its support. The container preferably includes a closure or seal capable of being fractured or punctured. The support includes means for fracturing or puncturing the closure when it is mounted.

An added feature of the present invention lies in the sealing of the pressurized material by the dispensing mechanism after the container closure or seal has been fractured.

Figure 3 is a modification of Figure 2 in partial cross section.

Figure 4 is a perspective of a seal puncturing element shown in Figure 3.

Figure 5 is a back and side perspective of the supporting casing shown in Figures 1 and 2.

Figure 6 is a plan view of a pressurized disposable container.

Figure 7 is a perspective of a cabinet 'structure'containing a plurality of the units shown in Figures 1-and'2.

in the arrangement of structure disclosed hereinl have provided a detachable hanger supportltl provided at its back portion 11 with an inset 12 having an inner peripheral groove 13 along the back sides and top of inset 12. This inset 12 and groove 13 permits the support 1% to be easily mounted on a plate bracket 9 shown in dotted outline. Conventional bracket locking means may be added to prevent vandalism or unauthorized removal. This support 16 may be of cast metal or molded plastic and formed with a hollow portion 14 within which is mounted or molded a metal or plastic dispenser tube holder 15.

As illustrated in Figure 2, the uppermost end 16 of tube 3.5. is internally threaded to receive in screw-on fashion the cap end 17 of replaceable pressurized tube 17. The tube 17 is pressurized and contains a material in the nature of gas pressurized grease, mayonnaise, soap, toothpaste, shaving cream or many like ingredients for use in the home and industry. The upper rim section 18 of support 1 3 forms the mouth of the hollow portion 14- and is provided with internal screw threads 19 adapted to fit the externally threaded open end 20 of a removable covering dome 21. Centered within the open end 16 of tube 15 is a needle 22 secured to tube 15 at its base 23 by any suitable means, or else is formed integral with the tube structure. The needle 22 is provided with a serrated edge or enlargement 24 to prick and otherwise cut the seal 25 in the cap end 17" of tube 17. T his breakage of seal 25 allows the gas pressure in tube 2.7 to expand and force the tube contents out and into the tube 15 which is supported in fluid tight relationship thereto.

In the modified structure shown in Figures 3 and 4 the needle 22 is secured to a perforated plate 26 which is insertable in the open end 16 of tube 15 and rests on an integral tube shoulder 27. This modified plate structure 26 is the most desirable form from the standpoint of manufacture.

The dispensing mechanism includes a sleeve 39 projecting inwardly from the wall 29 within the horizontal end of the angular tubular member 15. The sleeve 30 seals against the tube 15 with a leak proof connection. The sl eve 39 also projects outwardly from the wall 29, and forms a hollow passage through the Wall 29 in sealed relation to the angular tube 15. Obviously the parts may be made integral if desired.

The inner end (right end in the drawings) of the tubular member 3% includes an inwardly directed flange forming a shoulder which acts as a valve seat 32 normally engaged by a valve 34. The valve 34 is provided with a valve stem 33 extending loosely through the tubular sleeve 3% by means of which the valve may be operated. When the valve 34 is open, a passage is provided past the valve 34, through the sleeve 30, and into the interior of the nozzle housing 31.

The valve stem or push rod 33 extends through th nozzle housing 31 and is provided at its outer end with a push button 35. A spring 36 is interposed between the inwardly directed flange forming the shoulder or valve seat 32 and against'a stop pin or enlargement 37 3 on the push rod 33. Normally the spring 36 holds the valve 34 against its seat 32. Upon application of pressure on push button 35 the push rod 33 moves inwardly compressing spring 36 and opening valve 34 to permit an outflow of pressurized flowable material from tube and tube 30 into the nozzle housing 31. The pressurized materials then are forced or flow through the open'passageway 38 in nozzle housing 31.

The nozzle housing 31 generally is provided with an vinternal circular flange 39 which is in tight fitting relationship to the tubuluar wall 30. This flange 39 is shown in a slip-on relationship'but may be provided with threads fitting corresponding threads on tube 39, if desired. An

.outer circular flange 40 'is provided to cover. flange 39 the same.

'As illustrated in Figure 7 'there ;is provided in the cabinet 43 and on the door 44 a plurality of dispenser units of the character herein described. A plurality of brackets are mounted on the door panel 44 for holding the plurality of supports 10 in the manner as provided for in'Figures 2and 5, as described. As illustrated, the nozzle housings 5 1 with corresponding flange members 39 and 40 are fitted over the outwardly extended ends of tubes 30 which protrude from cooperative holes in the door 44. A conventional snaplatch 45, or other fastening means, is used to hold or look the door 44 in a closed position.

In the above disclosure the entire structure is formed of a light metal. However, the structural parts may be molded or cast from plastic or the structure may be built of a combination of the separate parts formed from a plastic and metal. From the above description the operation of the structure is apparent.
